Answer:
The short leg is 7 because half of 14 is 7 and the hypotenuse is always twice as long as the shortest one.
The required short leg is 7inches.
Given that,
Hypotenuse = 14 inches,
In triangle 30-60-90
We have to determine,
By using figure find the short leg.
According to the question,
A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º.
The triangle is special because its side lengths are always in the ratio of 1: √3:2.
The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given.
The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.
Therefore,
The hypotenuse is always twice as long as the shortest one.
Where, Hypotenuse = 14inches
Then,
[tex]Hypotenuse = 2 \times short \ leg \\\\14 = 2 \times short \ leg\\\\short\ leg = \dfrac{14}{2}\\\\short \ leg = 7[/tex]
Hence, The required short leg is 7inches.

Latesha needs to simplify a polynomial expression for homework
16x^2y/ 24xy^3
What should Latesha write on her homework paper as the correct answer
A. 2x/3y^2
B. 2y^2/ 3x
C. 3y^2/ 2x
D. 3x/2y^2
A. 2x/3y^2
HOPE THIS WILL HELP YOU
The correct answer that Latesha should write on her homework paper is 2x/3y2. Hence, the correct option is A.
The polynomial expression that Latesha needs to simplify is 16x^2y / 24xy^3. To simplify this expression, each term in the numerator should be divided by each corresponding term in the denominator that it is divisible by. Her steps should be as follows:
Divide both coefficients (numbers) by their greatest common divisor, which in this case is 8. So, 16 divided by 8 is 2, and 24 divided by 8 is 3.
Look at the powers of x and y and simplify. Subtract the exponents of like bases (16x2y has x2 and 24xy3 has x1, so you subtract 1 from 2 and get x to the power of 1, or just x).
For y, since y is on the top and bottom, subtract the exponents (1 - 3 = -2), which means y squared will be in the denominator.
Putting it all together, you get 2x / 3y2
which corresponds to answer choice A. 2x/3y2.
Therefore, the correct answer that Latesha should write on her homework paper is A. 2x/3y2.

How many hours worked is 1:45-4:00?
Answer:
2 1/4 h = 2.25 hStep-by-step explanation:
From 1:45 to 4:00 is:
15 min to 2:00
from 2:00 to 4:00 is 2h
We know 1h = 60min, therefore 1min = 1/60 h
2h and 15min = 2h + 15/60 h = 2h + 1/4 h = 2 1/4h = 2.25h
which equation has the steepest graph
Answer:
Answer: A. Y= -10x -4.
Step-by-step explanation:
Steeper line : is a line which is closed to y-axis, or closed vertically.
Since, the standard form of a line is,
y = mx + c
Where m is the slope,
If the absolute value of the slope ( that is, |m| ) is maximum then it is called it has the steepest graph.
For, y=-2x+6,
The absolute value of slope = 2,
For, y =8x-1,
The absolute value of slope = 8,
For, y=-10x-4,
The absolute value of slope = 10,
For, Y=7x+3,
The absolute value of slope = 7,
Since, 2< 7 < 8 < 10
Hence, the line y = -10 x - 4 is closest to y-axis,
⇒ Line y = -10 x - 4 has the steepest graph.
A steeper line is one with a greater absolute slope value. Among the provided equations, y = -10x - 4 has the steepest graph due to its absolute slope value of 10.
The correct answer is option A.
A steeper line in the context of linear equations can be understood as a line that is closer to the y-axis or one that has a more significant vertical incline. The steepness of a line is determined by its slope, represented as 'm' in the standard linear equation form, y = mx + c. The slope 'm' quantifies the rate at which the line rises or falls as it moves horizontally along the x-axis. The greater the absolute value of the slope (|m|), the steeper the line.
To identify the steepest line among several equations, one must calculate and compare the absolute values of their slopes. Let's evaluate a few examples:
For y = -2x + 6, the absolute value of the slope is |2|.
For y = 8x - 1, the absolute value of the slope is |8|.
For y = -10x - 4, the absolute value of the slope is |10|.
For y = 7x + 3, the absolute value of the slope is |7|.
Comparing these absolute values, we find that 2 < 7 < 8 < 10. Therefore, the line with the steepest graph is y = -10x - 4. This line is closest to the y-axis, indicating the most significant vertical incline among the given equations.
Therefore, from the given options the correct one is A.

Using rigid motion, which statement is true about the triangles?
Answer:
(b) ABC = FED
Step-by-step explanation:
The rigid motion concept implies that you move your points relative to another. That also means the naming of the objects (in this case triangles) has to be consistent.
By naming the first triangle ABC, you start by the lower-right corner of the triangle, go up then finish on the left-most point.
So, to name the other triangle in rigid-motion manner, you have to follow the same sequence... so it is F first, then E then D... so FED.

1814400
Step-by-step explanation:
* Lets explain how to solve the problem
- Permutation is the act of arranging the members into order
- The number of permutations of n members taken r at a time is
denoted by nPr
- nPr = n!/(n - r)! , where n! means n(n - 1)(n - 2)(n - 3) ......... × 1
* Lets solve the problem
- There are eleven people on a softball team
∴ n = 11
- There are nine different positions
∴ r = 9
∴ The number of ways can be made = 11P9
∵ 11P9 = 11!/(11 - 9)! = 11!/2! = 19958400
* The number of total arrangements of the player is 19958400
- If Amy does not want to play pitcher
∵ They are 11 players
∴ The number of players can be pitch = 11 - 1 = 10
* If Amy does not want to play pitcher, then there are now 10 people
available to pitch
- Assuming the pitcher has already be chosen
∴ There are 10 remaining players
∵ The positions are 9
∴ The remaining positions = 9 - 1 = 8
* There are 8 remaining positions
- Lets find how many ways to arrange the remaining positions
∵ n = 10
∵ r = 8
∴ 10P8 = 10!/(10 - 8)! = 10!/2! = 1814400
* The number of ways to arrange the remaining players is 1814400

A) 12°
B) 26°
C) 52°
D) 64°
Answer:
Option B. [tex]26\°[/tex]
Step-by-step explanation:
step 1
Find the measure of angle EBD
we know that
[tex]m<EBD+m<CBD+m<ABE=180\°[/tex]
remember that
[tex]m<EBD=m<CBD[/tex]
[tex]m<ABE=52\°[/tex]
substitute the values
[tex]2m<EBD+52\°=180\°[/tex]
[tex]2m<EBD=180\°-52\°[/tex]
[tex]m<EBD=128\°/2=64\°[/tex]
step 2
Find the measure of the angle EDB
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
In the right triangle BED
[tex]m<EBD+m<BED+m<EDB=180\°[/tex]
we have
[tex]m<EBD=64\°[/tex]
[tex]m<BED=90\°[/tex]
substitute
[tex]64\°+90\°+m<EDB=180\°[/tex]
[tex]m<EDB=180\°-(64\°+90\°)=26\°[/tex]
Answer:
B.[tex]26^{\circ}[/tex]
Step-by-step explanation:
We are given that a triangle ABD, BE is perpendicular to AD and angle EBD is congruent to angle CBD.
[tex]\angleABE=52^{\circ}[/tex]
We have to find the measure of angle EDB.
Let [tex]\angle EBD=x[/tex]
Then, [tex]\angle CBD=x[/tex] because angle EBD is congruent to angle CBD.
[tex]\angle ABE+\angle EBD+\angle CBD=180^{\circ}[/tex] (linear sum)
[tex]52+x+x=180[/tex]
[tex]2x=180-52=128[/tex]
[tex]x=\frac{128}{2}=64^{\circ}[/tex]
In triangle EBD
[tex]\angle BED=90^{\circ}[/tex]
[tex]\angle EBD=64^{\circ][/tex]
[tex]\angle EBD+\angle BED+\angle EDB=180^{\circ}[/tex] (sum of angles of triangle )
Substitute the values then we get
[tex]64+90+\angle EDB=180[/tex]
[tex]154+\angle EDB=180[/tex]
[tex]\angle EDB=180-154=26^{\circ}[/tex]
Hence, [tex]m\angle EDB=26^{\circ}[/tex]

Patricia compró 10 estampillas de correos unas de $3.00 y otras de $1.00. Si pago con $18.00 en total. ¿Cuántas pago por cada una? (Hacer el problema con uno de los varios sistemas de ecuaciones)
Answer:
Entonces Patricia necesitara 4 estampas de $3 dolares y 6 estampas de $1 dolar
Step-by-step explanation:
Cuatro estampas de tres dolares cada una es:
3 × 4 = 12
Ahora necesitamos encontrar cuantas estampas mas Patricia puede comprar. Podemos hacer esto restando 12 a 18, que es el costo total de las estampas menos del valor encontrado
18 - 12 = 6
Ahora sabemos que Patricia necesita 6 dolares de estampas ($1 estampas) para acompletar las 10 estampas dando un total de $18 dolares.
6 × 1 = 6 < sumar 6 de 12
12 + 6 = 18
Entonces Patricia necesitara 4 estampas de $3 dolares y 6 estampas de $1 dolar
To solve this problem using a system of equations, we can let x represent the number of stamps that Patricia bought for $3.00 and y represent the number of stamps she bought for $1.00.
Explanation:To solve this problem using a system of equations, we can let x represent the number of stamps that Patricia bought for $3.00 and y represent the number of stamps she bought for $1.00. The problem tells us that Patricia bought a total of 10 stamps and paid a total of $18.00. Therefore, we can set up the following system of equations:
x + y = 10
3x + y = 18
To solve this system, we can use the substitution or elimination method. Let's use the substitution method. From the first equation, we can solve for x in terms of y: x = 10 - y. Now we can substitute this expression for x in the second equation:
3(10 - y) + y = 18
30 - 3y + y = 18
30 - 2y = 18
-2y = -12
y = 6
Substituting this value of y back into the first equation, we can find the value of x:
x + 6 = 10
x = 4
So Patricia bought 4 stamps for $3.00 each and 6 stamps for $1.00 each.

which ordered pair is a solution to the equation
y= 4x+15
An ordered pair is a solution to the equation y = 4x + 15 if when its elements are substituted into the equation, both sides of the equation hold equal. For instance, the ordered pair (2,23) is a solution to this equation.
Explanation:The question is asking which ordered pair is a solution to the linear equation y = 4x + 15. An ordered pair consists of values of x and y that make this equation true. Therefore, we plug in the values of the ordered pair into the equation.
For example, if we have the ordered pair (2,23), we substitute the x value (2) and y value (23) into the equation: y = 4x + 15 becomes 23 = 4*2 + 15. By doing the calculation, we find that the left side of the equation equals the right side, therefore, (2,23) is a solution for the equation y= 4x+15.

The ordered pair (2, 23) is a solution to the equation y = 4x + 15. By substituting x = 2, the corresponding y value is 23, validating the solution in the linear relationship.
To find an ordered pair that is a solution to the equation y = 4x + 15, we can choose values for x and compute the corresponding y value.
Let's try x = 2:
y = 4(2) + 15 = 8 + 15 = 23
So, the ordered pair (2, 23) is a solution to the equation.
In this context, for any chosen x, plugging it into the equation and calculating y will yield a valid solution. The equation represents a linear relationship where y is four times x plus 15. Therefore, any pair of x and y that satisfies this relationship is a solution to the equation. The solution set consists of an infinite number of ordered pairs, each representing a point on the graph of the linear equation.

Hence, the number is in the form of:
a+ib
where
[tex]a=\dfrac{8}{3}[/tex] which is a rational number and hence belong to real number
and
[tex]b=\sqrt{\dfrac{7}{3}}[/tex] which is a irrational number and hence belong to a real number.
Baseball player hits a ball on an angle of 54° and a height of 4 1/2 feet if the balls initial velocity after being is 152 ft./s if no one catches the ball when will hit the ground
The answer is:
The ball will hit the ground in 7.69 seconds.
Why?To solve this problem, we need to apply the following projectile motion equation:
[tex]y=vo*sin(\alpha)*t-\frac{1}{2}gt^{2}[/tex]
To calculate when the ball wil hit the ground, in other words the time of flight, we need to make "y" equal to 0, and considerate the initial height, so, we have:
[tex]0=initialheight+vo*sin(\alpha)*t-\frac{1}{2}gt^{2}[/tex]
Then, we are given the following information:
[tex]InitialHeight=4.5feet\\\alpha =54\°\\vo=\frac{152ft}{s}[/tex]
Now, substituting and solving, we have:
[tex]-(\frac{1}{2})*\frac{32.15ft}{s^{2}}*t^{2}+\frac{152ft}{s}*sin(54\°)+4.5ft\\\\-16.07\frac{ft}{s^{2} }*t^{2}+122.97\frac{ft}{s}*t +4.5ft=0[/tex]
We have a quadratic equation, where:
[tex]a=-16.07\\b=122.97\\c=4.5[/tex]
Now, using the quadratic equation to find the values of "t" , we have:
[tex]\frac{-b+-\sqrt{b^{2}-4ac} }{2a}[/tex]
Substituting we have:
[tex]\frac{-122.97+-\sqrt{(122.97)^{2}-4*(-16.0)*(4.5)} }{2*(-16.07)}\\\\\frac{-122.97+-\sqrt{(122.97)^{2}-4*(-16.07)*(4.5)} }{2*(-16.07)}=\frac{-122.97+-\sqrt{15121.62+289.26}}{-32.14}\\\\\frac{-122.97+-\sqrt{15121.62+289.26}}{-32.14}=\frac{-122.97+-(124.14)}{-32.14}[/tex]
[tex]t_1=\frac{-122.97+124.14}{-32.14}=-0.04\\\\t_2=\frac{-122.97-124.14}{-32.14}=7.69[/tex]
Therefore, since the time cannot be negative, we have to discard "t1", so, the answer is: 7.69 seconds
Hence, the ball will hit the ground in 7.69 seconds.
Have a nice day!
